prost-helper 0.1.0

A set of prost helper functions to make prost generated code easy to work with.

If you use prost-serde to build your protobuf files, mostly you need this crate to provide functions for is_zero and deserialize_null_default.

You can also use the macros to convert protobuf messages to / try_from Vec<u8>.

For example, if prost generated a data struct Hello, You can use the macros to generate From and /TryFrom respectively, and then use them:

use prost_helper::{prost_into_vec, vec_try_into_prost};
use prost::Message;

#[derive(Clone, PartialEq, prost::Message)]
pub struct Hello {
#[prost(string, tag = "1")]
pub msg: String,
}

prost_into_vec!(Hello, 32);
vec_try_into_prost!(Hello);

fn send_hello(data: Vec<u8>) {
unimplemented!();
}

let hello = Hello::default();
send_hello(hello.into());
